I don’t think it’d be that hard to prove that an aftermarket ECU caused an engine failure. I’m not saying that the ECU caused it, I’m just citing the obvious connection. On the other hand, I’m doubtful that Active would release software that blows engines up.
Obsidian, had you spoken with AAW about the situation?
As far as getting Dinan parts, I’d say Sewickley a safe bet.
